Solution
The correct option is A 5.5 cm
Given, ∠ACD=90°, CD = 2.3 cm.
Steps of construction:
Step 1: Keeping AC as the base line, construct an angle of 90° at the point C. Extend the line.
Step 2: Keeping C as the centre, construct an arc of radius 2.3 cm on the extended line.
Step 3: Join A to D. Measure the length of AD. It will be approximately 5.5 cm.
After construction, we get the following figure.
The length of the line segment AD will 5.5 cm
